If you stayed in Canada till Oct 2020 and only be outside from Oct 2020 - Feb 2023 (when you plan to travel back), you still meet your RO.
Since you meet your RO and has a valid PR card, you should be able to enter without issue.
Immigration can still ask questions but that should not have any concern on you meeting your RO.
You can apply to sponsor your spouse and children via outland once you moved back to Canada (if they don't have approved TRV by then).
thank you so much all your info helps me well understand everything.
